Sql server could not start?

[Alistair]

Hi, I'd like to ask you a question about a particular case, I'd like to know sql server could not start? Thank you for giving me your opinion quickly because I stress.

This is an authentication problem due to a network interface that loops to infinity.

How I solved it:

1. Start the registry
2. Open the key HKLM \ System \ CurrentControlSet \ Control \ LSA
3. Add a DWORD value called "DisableLoopbackCheck"
4. Set the value to 1
5. Restart the server
